CCP-C Critical Care Prep Exam Questions & Answers 2026 (21–30)

Question 1

A 76-year-old male patient with a history of congestive heart failure is being transported to a medical facility. He exhibits symptoms of shortness of breath and leg muscle weakness. Lab results indicate a serum potassium level of 3.1 mEq/L. Which of the following symptoms is most likely to be present in this patient? Patient Age History Symptoms Serum Potassium Level (mEq/L) 76 Congestive Heart Failure Shortness of breath, leg muscle weakness $$3.1$$

TheoryPractice · Accepted Answer

Fatigue. Hypokalemia is indicated by a serum potassium level below the normal range of 3.5-5.5 mEq/L. Common symptoms include muscle weakness, fatigue, and potential arrhythmias. The patient's symptoms and lab results are indicative of hypokalemia.

Question 2

Your 58-year-old male patient has been admitted to the ICU with severe dehydration. You decide to administer intravenous fluids. Which type of fluid, if used improperly, could lead to metabolic alkalosis due to changes in electrolyte balance? Type of Fluid Potential Acid-Base Imbalance Example Isotonic fluid None 0.9% Normal Saline Hypotonic fluid Hyponatremia leading to metabolic alkalosis 0.45% Saline Hypertonic fluid Hypernatremia leading to metabolic acidosis 3% Saline

TheoryPractice · Accepted Answer

Hypotonic fluid. Answer: Hypotonic fluid Administering hypotonic fluids can cause hyponatremia due to the dilution of sodium in the blood. This can potentially lead to metabolic alkalosis as the body tries to compensate for the low sodium levels, possibly causing an electrolyte imbalance and affecting acid-base status.

Question 3

For a 6-month-old child experiencing cardiac arrest due to respiratory failure during ground transport, certain criteria must be met to initiate ECMO. Based on the given parameters, which of the following is NOT a suitable indicator for ECMO support? Parameter Value Age 6 months PaO2 45 mmHg PaCO2 55 mmHg pH 7.20 Persistence without response to maximal intervention True Cardiac Output Significantly reduced

TheoryPractice · Accepted Answer

$$PaO_{2}$$ of 45 mmHg. A $$PaO_{2}$$ of 45 mmHg can be a common finding in severe respiratory failure, indicating the need for intervention. However, severely reduced $$PaO_{2}$$ itself is not typically a standalone exclusion criterion for ECMO initiation in respiratory failure. Other parameters, such as sustained metabolic acidosis indicated by pH, significantly reduced cardiac output, and persistent clinical deterioration despite maximal interventions, align more closely with ECMO requirements.

Question 4

A 38-year-old male firefighter is rescued from a burning building and shows signs of severe smoke inhalation and potential airway burns, requiring immediate advanced airway management.

Which consideration is most appropriate for performing intubation in this scenario?

TheoryPractice · Accepted Answer

Prepare a smaller endotracheal tube due to potential airway edema. In cases of smoke inhalation and potential airway burns, airway edema is a significant concern, warranting the preparation of a smaller endotracheal tube. Traditional endotracheal tubes may be too large due to tissue swelling, and ensuring proper breathing is essential.

Question 5

You are caring for a 30-year-old female patient who has just undergone surgery with general anesthesia. Post-operatively, she experiences rapid heart rate, muscle rigidity, elevated body temperature, and increased $$CO_{2}$$ production. What is the recommended treatment for managing this patient's condition?

TheoryPractice · Accepted Answer

Dantrolene sodium 2.5 mg/kg IVP. The patient is displaying signs and symptoms consistent with malignant hyperthermia, a rare but serious reaction to certain anesthetic agents. The first line treatment for this condition is administration of dantrolene sodium at a dose of 2.5 mg/kg IVP. This treatment should be followed by supportive measures such as rapid cooling, oxygen administration, and monitoring of electrolytes and acid-base balance.

Question 6

A 35-year-old diabetic patient presents to the emergency department with nausea, vomiting, and abdominal pain. You obtain the following arterial blood gas values and note the presence of ketones in the urine. Component Value (Patient A) Normal Range pH 7.28 7.35 - 7.45 Bicarbonate (HCO3-) 12 mEq/L 22 - 26 mEq/L Ketones (urine) Positive Negative

TheoryPractice · Accepted Answer

Metabolic ketoacidosis. The low pH and decreased bicarbonate level indicate an acidosis, consistent with metabolic ketoacidosis due to the positive ketones in the urine. Respiratory acidosis would typically have elevated $$CO_{2}$$ levels, while lactic acidosis would occur with sepsis or liver disease.

Question 7

You are managing a critically ill 45-year-old male in the ICU who is mechanically ventilated. The ETCO2 monitor shows an elevated level of 60 mmHg. Which of the following causes should you consider?

TheoryPractice · Accepted Answer

Rebreathing due to ventilator settings. Answer: Rebreathing due to ventilator settings When ETCO2 is elevated in a ventilated patient, consider whether the patient is rebreathing expired carbon dioxide, often due to incorrect ventilator settings or equipment malfunction. Other causes could include decreased respiratory rate or tidal volume and increased metabolic rate.

Question 8

You are assessing a 45-year-old male patient with a severe neck injury resulting from a vehicular crash. What mnemonic can assist in determining the most suitable intubation method given the patient's limited neck mobility and potential airway complications?

TheoryPractice · Accepted Answer

HEAVEN. Answer: HEAVEN. The mnemonic HEAVEN is particularly useful in assessing factors such as neck mobility, hypoxemia, and anatomic disruption, which are crucial in determining whether video or direct laryngoscopy is appropriate during intubation.

Question 9

You are treating a 55-year-old male who has just suffered an acute myocardial infarction and is hypotensive with a blood pressure of 85/55 mmHg and a heart rate of 120 beats per minute. Which of the following treatments should be administered immediately to stabilize the patient's hemodynamic status?

TheoryPractice · Accepted Answer

Dopamine. Dopamine is commonly used to support blood pressure in patients who are hypotensive due to cardiogenic shock or low cardiac output situations, such as following an acute myocardial infarction. It acts as a vasopressor to increase cardiac output and stabilize blood pressure. Aspirin is used for its antiplatelet effects in acute myocardial infarction but does not address hypotension. Loratadine is an antihistamine, not indicated for this scenario. Furosemide is a diuretic and is not appropriate for immediate hemodynamic stabilization in acute heart failure.

Question 10

During an abdominal surgery on a 45-year-old male, the medical team notices variable blood pressure readings throughout the procedure. What is the most likely cause of these variations?

TheoryPractice · Accepted Answer

Organ pressure by instruments. Organ pressure by surgical instruments is the most common cause of variable blood pressure readings during surgery, similar to how umbilical cord compression causes variable decelerations of fetal heart rate during labor. Patient movement is highly unlikely during surgery due to anesthesia. Surgical lighting and external noise typically do not impact blood pressure in this manner.
